Describe the Republican sniper as he lay hiding on the rooftop.

The sniper was laying on a rooftop near O'Connell Bridge. He had his rifle set next to him, and he was carrying his field glasses on his shoulder. The sniper is described as young, evidenced by the fact that he looked like a "student". His eyes are described as having "the cold gleam of the fanatic", deepset and thoughtful, eyes used to looking at death.

The sniper was eating. He also had a flask of whiskey. He wanted a cigarette and took the chance of lighting it, an act that was quickly followed by a bullet aimed his way.
